St. Jago was the largest island of Cape Verde Islands.
The island was discovered by António da Noli in around 1460 who built a garrison in Ribeira Grande. Transcontinental slavery made Ribeira Grande the second richest city in the Portuguese realm. Portugal was unable to protect its colonies because the English, Dutch, French and Spanish took over the slave trade and the island was later raided by pirates. The EITC merchant ship Wicked Wench docked on St. Jago on her maiden voyage to the Caribbean.
